网络化控制系统的预测控制方法设计

Design of Networked Predictive Control in Networked Control Systems

网络化控制系统(NCSs)是一种通过实时化网络进行数据传输的控制系统。控制系统中的传感器、控制器、执行器等往往通过网络连接起来形成闭环控制系统。然而实际系统中由于带宽限制等客观因素,存在有因网络诱导延迟而引起的系统性能下降问题。考虑了前向通道,反馈通道中同时存在网络诱导时延情况下的网络预测控制(NPC)设计问题,提出了一种新的网络预测控制方法,用以克服网络诱导时延对系统性能带来的影响。

Networked control system （NCSs） is a kind of control system whose data was communicated by real-time network. The sensor, controller and actuator always connect by network to be a close-loop control system. However, since the objective factors such as network bandwidth limitation, there is the system performance degradation in the real systems. This paper is concerned with the net-worked predictive control design of networked control systems with network-induced delay in both forward and feedback channels. A novel networked predictive control （NPC） approach is proposed to compensate the effects of network-induced delay.
